文摘

By selection of different charge-balancing anionic frameworks and different host-to-guest ratios, the photosensitizer-dye cation [Cu(dmp)₂]⁺ (dmp = 2,9-dimethyl-1,10-phenanthroline) has been embedded in a series of three-dimensionalhost structures. It occurs with variable geometry in different states of aggregation, including weakly interactingmonomers, isolated dimers, columns, and layers. A large variation in its emission lifetime is correlated with therelative energy level spacings of the guest- and host-framework components. In a fully saturated host framework,the lifetime exceeds values reported for a series of conventional Cu(dmp)₂ salts.
