Abstract

Reversible photochromic reactions can be coupled to carrier-mediated transport processes in membranes to bring about the separation or concentration of selected permeants. Carbon monoxide has been pumped against of fourfold concentration gradient by differentially illuminating a hemoglobin membrane. The extent of concentration of photochromic ligands increases with light intensity and is reversible. Nonphotochemically sensitive ligands can also be transported by coupling with phostosensitive carrier-mediated systems.

摘要

可逆光致变色反应可与膜中载体介导的转运过程相偶联，以实现特定渗透物的分离或浓缩。通过对血红蛋白膜进行差异光照，一氧化碳已被逆着四倍浓度梯度进行泵送。光致变色配体的浓缩程度随光强度增加而增加，并且是可逆的。非光化学敏感配体也可通过与光敏载体介导系统偶联进行转运。
