Experimental Section General. All air-sensitive reactions were performed under a nitrogen atmosphere using standard Schlenck techniques. CH 2 Cl 2 was distilled from CaH 2 , Et 2 O from sodium/benzophenone, and MeOH from Mg(OEt) 2 prior to use. Other solvents and all standard reagents were purchased and used as received. 1 H and 13 C{ 1 H} NMR spectra were recorded at 300 MHz and 75 MHz, respectively, on a Varian 300 spectrometer operating at 298 K. If the signals were detected, they are

UV/Vis spectra were recorded on a Cary 50 scan UV-visible spectrophotometer and solid state UV/Vis spectra were recorded on a Varian Cary 5 UV-Vis-NIR spectrophotometer. Elemental microanalyses were performed by Dornis und Kolbe, Mikroanalytisches Laboratorium, Müllheim a/d Ruhr, Germany. 1-benzyl-4-phenyl-1,2,3-triazole (L1) 1 1 H NMR (acetone-d 6 , 298 K): δ = 8.37 (s, 1H, triazole-H), 7.90 (ps d, 2H, 4-phenyl-H ortho ), 7.45-7.26 (m, 8H, ArH), 5.68 (s, 2H, CH 2 ) ppm; 13 C NMR (acetone-d 6 , 298
