Photoluminescence and optical waveguiding characteristics of bisalkoxy tin(IV) porphyrin microcrystals.

: Guide me: Laser confocal microscope photoluminescence (LCM-PL) and optical waveguiding characteristics for tin(IV) porphyrin-based microcrystalline rods and plates were investigated. The efficiency of optical waveguiding for the rods (0.04 μm(-1)) was five times better than for the plate, due to stronger π-π interaction and a short layer distance (3.035 vs. 3.328 A).
