Hara, Nobuyuki published the artcileInter- and intramolecular excimer circularly polarised luminescence of planar chiral paracyclophane-pyrene luminophores, Computed Properties of 36428-96-3, the main research area is paracyclophane pyrene luminophore intramol excimer.
Two types of planar chiral [2,2]paracyclophane-pyrene luminophores (1 and 2) with different binding positions of the fluorescent pyrene units were synthesized. (R)/(S)-1 with 1-pyrene units exhibited green intermol. excimer circularly polarised luminescence (CPL) at 530 nm in the KBr-pellet, but exhibited no CPL signal in dilute CHCl3 solution In contrast, (R)/(S)-2 with 2-pyrene units exhibited a blue intramol. excimer CPL at 450 nm in CHCl3 solution This is the first example of using the binding position of pyrene and the external environment to tune the type (inter- or intramol.) and chiroptical sign of excimer CPL.
RSC Advances published new progress about Circular dichroism. 36428-96-3 belongs to class chlorides-buliding-blocks, name is Pyrene-2-carboxylic acid, and the molecular formula is C17H10O2, Computed Properties of 36428-96-3.
