ionic liquids based on DABCO-derived quaternary ammonium salts: A promising reaction medium in gaining access

Muhammad Faisal, Azeem Haider, Quret ul Aein, Aamer Saeed, Fayaz Ali Larik

Frontiers of Chemical Science and Engineering 2019, Volume 13, Issue 3,   Pages 586-598 doi: 10.1007/s11705-018-1788-6

Abstract: Owing to the directional H-bonding, coordination and -stacking abilities, terpyridines have been widely used as supramolecular tectons in molecular architectures, skeletons in molecular devices and metallopolymers, and are gaining importance in medicinal chemistry. In this paper, we have synthesized, characterized and applied deep eutectic ionic liquids (DEILs) based on 1,4-diazabicyclo[2.2.2]octane; triethylenediamine (DABCO)-derived quaternary ammonium salts for the preparation of terpyridines. These DEILs were synthesized through -alkylation of DABCO with haloalkanes (1-bromopentane or 1-bromoheptane) followed by mixing and heating with methanol or polyethylene glycol as a hydrogen bond donor. The synthesized DEILs were structurally characterized by IR and NMR. The formation of deep eutectic solvent was confirmed by freezing point depression, it composition was investigated through phase diagram, and its thermal stability was determined through differential scanning calorimetry, derivative thermogravimetry and thermal gravimetric analysis studies. Further, theseDEILswereinvestigatedfor theireffectivenesstowards synthesis of 2,2′:6′,2″-terpyridine, 3,2′:6′,3″-terpyridineand 4,2′:6′,4″-terpyridinederivatives through Kröhnke reaction. The results show that these three types of terpyridines can be obtained in reasonable yields (80% 97%) by the one-pot reaction of 2-, 3- or 4-acetylpyridine with a variety of aromatic aldehydes in the presence of DEIL as a reaction medium, sodium hydroxide as a base and ammonium acetate as a cyclizing agent. This methodology is highly efficient and cost-effective for synthesis of symmetrical as well as unsymmetrical terpyridines. Importantly, these DEILs can be reused several times without an obvious loss of activity and are non-toxic, low-volatile, biodegradable and highly thermally stable. Therefore, these DEILs as a non-conventional reaction medium for the synthesis of terpyridines provides appealing opportunities to be investigated in the domain of green synthesis.

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 6,   Pages 801-812 doi: 10.1631/FITEE.2300196

Abstract: In a multi-user system, system resources should be allocated to different users. In traditional communication systems, system resources generally include time, frequency, space, and power, so technologies such as time division (TDMA), frequency division (FDMA), space division (SDMA), code division (CDMA), and non-orthogonal (NOMA) are widely used. In , which is considered a new paradigm of the next-generation communication system, we extract high-dimensional features from signal sources in a model-based artificial intelligence approach from a semantic perspective and construct a model information space for signal sources and channel features. From the high-dimensional semantic space, we excavate the shared and personalized information of semantic information and propose a novel technology, named (MDMA)%29&ck%5B%5D=abstract&ck%5B%5D=keyword'>, which is based on the resource of the semantic domain. From the perspective of information theory, we prove that MDMA can attain more performance gains than traditional technologies. Simulation results show that MDMA saves more bandwidth resources than traditional technologies, and that MDMA has at least a 5-dB advantage over NOMA in the additive white Gaussian noise (AWGN) channel under the low signal-to-noise (SNR) condition.

Beamforming and fronthaul compression design for intelligent reflecting surface aided cloud radio access Research Article

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 1,   Pages 31-46 doi: 10.1631/FITEE.2100307

Abstract: Owing to the inherent central information processing and resource management ability, the is a promising network structure for an intelligent and simplified sixth-generation (6G) wireless network. Nevertheless, to further enhance the capacity and coverage, more radio remote heads (RRHs) as well as high-fidelity and low-latency fronthaul links are required, which may lead to high implementation cost. To address this issue, we propose to exploit the as an alternative way to enhance the C-RAN, which is a low-cost and energy-efficient option. Specifically, we consider the uplink transmission where multi-antenna users communicate with the baseband unit (BBU) pool through multi-antenna RRHs and multiple IRSs are deployed between the users and RRHs. RRHs can conduct either point-to-point (P2P) compression or Wyner-Ziv coding to compress the received signals, which are then forwarded to the BBU pool through fronthaul links. We investigate the joint design and optimization of user transmit beamformers, IRS passive beamformers, and noise covariance matrices to maximize the uplink sum rate subject to fronthaul capacity constraints under P2P compression and Wyner-Ziv coding. By exploiting the Arimoto-Blahut algorithm and semi-definite relaxation (SDR), we propose a successive convex approximation approach to solve non-convex problems, and two iterative algorithms corresponding to P2P compression and Wyner-Ziv coding are provided. Numerical results verify the performance gain brought about by deploying IRS in C-RAN and the superiority of the proposed joint design.
