Synthesis and characterisation of push–pull flavin dyes with efficient second harmonic generation (SHG) properties
Keyword(s):
We report push–pull flavins bearing different donor groups that exhibit high hyperpolarisabilities (β = 355–9550 × 10−30 esu) and decomposition temperatures thereby indicating their potential application as non-linear optical device materials.
