Can laser-driven bond activation in donor–π–acceptor chromophores reversibly tune their nonlinear optical response?

last month 1 9K Report

Can laser-driven bond activation in donor–π–acceptor chromophores reversibly tune their nonlinear optical response? Which mechanisms—such as bond isomerisation, conformational switching, or excited-state charge transfer—allow this without degrading the chromophore?

Verici pi ve alıcı kromoforlar arasında bağ aktivasyonu sağlandıktan sonra hem doğrusal hemde doğrusal olmayan optik tepkimeler geri dönüşümlü olarak ayarlanabilir. Lazer kaynağı ile gönderilen ışınların bağ aktivasyonunun uyumlu olması verici pi ve alıcı kromoforların sahip olduğu diğer özellikleri sağlamasına yardımcı olur.
