Homoleptic tungsten arylisocyanide complexes have remarkable spectroscopic and photophys. properties: metal-toligand charge-transfer absorption coeffs. on the order of 10^5 M^(-1) cm^(-1), luminescence quantum efficiencies as high as 25%, and excited-state lifetimes longer than 1 s. Moreover, the two-photon absorption cross sections of these complexes (1000-2000 10^(-50) cm^4 s photon^(-1) at 811 nm) are 10-100 times greater than those of many com. 2-photon dyes. We are working to understand these unique properties and to discover new mols. with enhanced characteristics. Our current efforts are aimed at prepg. fused-ring arylisocyanide ligands and developing protocols to use them in the synthesis of new homoleptic tungsten complexes.
