though 1,4-disubstituted 
 1,2,3-triazole rings have been utilized 
 as electronic bridges in the solution phase , the use of a triazole 
 ring to serve as an electronic bridge of small molecules in the crystalline 
 state has been underdeveloped . here 
 two compounds with a central 1,4-disubstituted 
 1,2,3-triazole ring are synthesized to investigate the electronic 
 bridging between terminal stilbazole and pyridine groups in the crystalline 
 phase . 
 the electronic properties of the molecules are characterized 
 through solution phase uv  vis spectroscopy , single crystal 
 x - ray diffractions , and density - of - state and gas - phase dft calculations . 
 we show that the electronic bridging behavior of a 1,4-disubstituted 
 1,2,3-triazole ring derived from a click reaction is maintained in 
 the solid state by rare head - to - head ( hh ) packing in noncentrosymmetric 
 crystal environments .
