Flash Pyrolysis – Synthetic and Mechanistic Aspects
CHIMIA, 1977 Some examples of synthetically useful flash pyrolysis reactions are presented, and the reaction mechanisms are discussed. Cyanocyclopentadienes, -indenes, and -pyrroles are produced by pyrolysis of the appropriate triazoloarenes or isatins, or as the ...

Advanced Functional Materials, EarlyView.A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a
