Synthesis of Novel Scolopendra-type Polydodecyloxybenzoyl[1,5]-diazocine as New Material for Optical Sensor

Synthetic strategies and diversification of dibenzo[1,5]diazocines

“…The changes in absorption behaviour are due to the protonation effect at the azomethine moieties which tunes the conjugation within the polymer. 44 The oxidation and reduction peaks for 6b are found at −0.51 and −0.76 V, respectively (vs. Ag/Ag + as the internal standard). 43 Under a similar synthetic protocol, the intermolecular cyclisation of 7a,b delivered polydibenzo [1,5]diazocines 8a,b in excellent yields (Scheme 2c).…”

“…The intermolecular cyclisation of 5a–c in refluxing trifluoroacetic acid (TFA) affords 6a–c in 55–78% yields (Scheme 2b). 43,44 The PDI values for 6a–c are 1.51, 1.67 and 1.60, respectively. The absorption spectrum of 6a in dichloromethane shows a maximum peak at 267 nm.…”
