BLUE ORGANIC LONG-PERSISTENT LUMINESCENCE VIA UPCONVERSION FROM CHARGE-TRANSFER TO LOCALLY EXCITED SINGLET STATE

Blue organic long-persistent luminescence via upconversion from charge-transfer to locally excited singlet state

Abstract Long-persistent luminescence (LPL) materials have applications from safety signage to bioimaging; however, existing organic LPL (OLPL) systems do not align with human scotopic vision, which is sensitive to blue light.We present a strategy Wine Glasses to blueshift the emissions in binary OLPL systems by upconverting the charge-transfer (CT

Ammonium 4-methoxybenzenesulfonate

The molecular structure of the title compound, NH4+·C7H7O4S−, is featureless [the methoxy C atom deviating 0.173 (6) Å from the phenyl mean plane] with interatomic distances and Sofa angles in the expected ranges.The main feature of interest is the packing mode.Hydrophilic (SO3 and NH4) and hydrophobi
