This article provides an overview and a critical evaluation on the synthesis and characterization of ladder polymers, with regard to such aspects as structural regularity and processibility of the materials. Hereby, the review focuses on synthetic principles defining further progress in the field of ladder polymer synthesis (Diels-Alder-polymerizations as a concerted process of ladder formation, the...
The network formation in the free-radical crosslinking polymerization and copolymerization of multivinyl compounds, especially including diallyl esters and dimethacrylates, was dealt with by focusing our attention on the mechanistic discussion on deviation from Flory-Stockmayer's (F-S) theory. First, the reasons for the greatly delayed gelation in diallyl polymerizations were discussed mechanistically...
The concept of using a molecular template to generate recognition sites for selective separations or reactions within a polymeric network is an exciting, challenging and far-reaching one. This review seeks to explain and define the concept and its components. It traces the early developments by the pioneers in the field and highlights the important advances made, or the key crossroads passed, in reaching...
The present review classifies, discusses and critically summarizes the results in the field of free radical polymerizations as well as of photocrosslinking and photografting reactions promoted by polymeric photoinitiators. Particular emphasis is given to the synthesis and structure-properties relations of the cited polymeric systems in order to optimize their molecular design for obtaining the desired...
Photosynthesis is attracting attention as an important model of artificial photochemical conversion system in relevant to solar energy conversion for new energy resources. In the photosynthesis, dioxygen evolution is the most important process which provides electrons to the whole photochemical system. Several proposals have been put forward to elucidate the mechanism in the dioxygen formation from...
