Rodlike macromolecules through spatial overlapping of thiophene dendrons.
Two novel dendritic macromonomers 7 and 8 functionalized with electroactive conjugated thiophene oligomers were synthesized by stepwise cross-coupling reactions and the introduction of a vinyl group at the focal point. Both macromonomers were polymerized into dendronized polymers 9 and 10 by using a radical polymerization method. The photophysical and redox behaviors of dendronized polymers 9 a...
متن کاملDendronized macromonomers for three-dimensional data storagew
A continuing trend in information storage is the desire for greater storage capacity, a feature that demands the development of both new storage techniques as well as new materials. One of the most promising approaches for achieving high density data storage is based on volume holography which allows data to be stored in 3 dimensions. This significant increase in capacity is in direct contrast ...
متن کاملComplex Macromolecular Architectures by Atom Transfer Radical Polymerization
Controlled radical polymerization has proven to be a viable route to obtain polymers with narrow polydispersities (PDI’s) and controlled molecular weights under simple reaction conditions. It also offers control over the chain‐ends of the synthesized polymer. Atom transfer radical polymerization (ATRP) is the most studied and utilized of these techniques. In this study ATRP has ...
متن کاملThe Effect of Storage Environment on Dimensional Changes of Acrylic Resin Post Patterns
Introduction: The purpose of this study was to compare dimensional changes of two types of auto polymerizing acrylic resin patterns (APARPs) in three different storing environments. Methods: 60 acrylic post and core patterns were made of two types of Duralay acrylic resins (Aria dent, Iran and Reliance, Dental Mfg. Co, USA) using a canine model. Then coronal, apical diameter and coronoapical le...
متن کاملEffect of Storage Conditions and Disinfection with 2% Deconex® on Dimensional Stability of Two Self-Cure Acrylic Resins
Background and Aim: There is a gap of information on the effect of time, disinfectant, and storage conditions on the dimensional stability of direct post patterns made of self-cure acrylic resins. This study assessed the effect of Deconex® and wet or dry stor-age conditions on the dimensional stability of post patterns made of Duralay and GC acrylic resins. Materials and Methods: Sixty spe...
