由Re（2，20-联吡啶-5，50-二羧酸酯）（CO）（3）Cl桥连配体和Cu（II）节点合成的含金属配位网络，[{Cu（DMF）（H2O）[ LRe（CO）（3）Cl]}中心点DMF]无限ReCu，经历不可逆的光诱导电荷转移过程。我们证明了使用时间分辨红外光谱的性质，这种光诱导的过程，以及如何，在适当的条件下，它是可能的，通过诱导的电荷转移过程中，启动不可逆的修改的晶体。因此，我们能够使用光诱导过程，这纯粹是由于配位网络的结构而产生的，在晶体上写入。
A metal-bearing coordination network synthesised from Re(2,20-bipyridine-5,50-dicarboxylate)(CO)(3)Cl bridging ligands and Cu(II) nodes, [{Cu(DMF)(H2O)[ LRe(CO)(3)Cl]}center dot DMF]infinity ReCu, undergoes an irreversible photoinduced charge transfer process. We demonstrate using time-resolved IR spectroscopy the nature of this photoinduced process and how, under suitable conditions, it is possible to initiate irreversible modification of the crystal through induction of the charge transfer process. As a result we are able to use the photoinduced process, which arises purely as a result of the structure of the coordination network, to write on crystals.
