Synthesis and photochromic properties of thiophene linked [2H]-chromenes

Article abstract of DOI:10.1080/10587250008023827

Successive coupling reactions (catalysed by Cu(I)/Pd(II) systems) between 8-bromo-3,3-diphenyl-[3H]naphtho[2,1-b]pyran, 2-methylbut-3-yn-2-ol and appropriate thiophene- or bithiophene halides afforded mono- or bichromophoric chromenes bearing a thienylethynyl or a bithienylethynyl group. Spectrokinetic study using flash photolysis conditions showed interesting photochromic properties regarding, especially, the 'colorability' of the new compounds.
