Abstract
This paper presents an attempt to develop a new system for fixing carbon dioxide from the atmosphere. The proposed molecular system has been designed to have the capacity to spontaneously bind CO from the atmosphere with high affinity. The molecular system is furthermore designed to have the ability to liberate CO at a later stage in the process, i.e., in a separate compartment. The liberated CO presents a carbon neutral way of obtaining pure CO. The proposed molecular system is based on a small stable organic molecule that potentially have two forms: one without bound CO and one with bound CO. One class of molecules that undergo a reaction compatible with our purposal is the merocyanine dyes that exhibit photochromic properties. Based on this structural class of molecules, a system for the potential fixing of CO has been developed.
