Dithienothiophene
WebThienothiophene usually refers to any of three structurally related derivatives of thiophene with the formula C 6 H 4 S 2.In order of importance, they are: thieno(3,2-b)thiophene, … WebThe U01 dye depicts IPCE of 70% at 400 nm–560 nm and peaks of 86% at 500 nm within the visible region. The sensitized YF02 dye reaches up to 75% at 350 nm-550 nm. The greater IPCE value of AK-01, TA-St-CA, YF02 and BA-03 in the UV zone suggested that these organic dyes successfully surpassed the dip of IPCE spectrum in that region.
