Organic Electro-Optic Materials

Synthesis and characterisation of push–pull flavin dyes with efficient second harmonic generation (SHG) properties

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.

Novel electro-optic chromophores based on substituted benzo[1,2-b:4,5-b′]dithiophene π-conjugated bridges

The electro-optic coefficient of benzo[1,2-b:4,5-b′]dithiophene unit (BDT)-based chromophores was improved to 102 pm V⁻¹ with suitable isolation groups and electron donors.
