Two categories of DAST derivatives were synthesized. For EO applications, the polyene analogues with increased double-bond number between two aromatic rings of DAST and fused-ring derivatives of DAST were prepared for larger β than DAST cation, and promising cations were found. For frequency conversion of diode lasers, substituted pyridiniums were investigated to obtain crystals better than inorganic compounds. By choosing proper counter anions, several SHG-active crystals without visible absorption have been found.
