In den letzten zehn Jahren wurden enorme Fortschritte bei der Synthese von Polymeren erzielt, die Hauptgruppen‐Elemente enthalten und über die typischen organischen Polymere hinausgehen. Einzigartige Eigenschaften, die sich aus drastischen Unterschieden in Bindung und molekularer Geometrie, elektronischer Struktur und chemischer Reaktivität ergeben, werden in den unterschiedlichsten Anwendungsbereichen genutzt. In dem Aufsatz werden die jüngsten Fortschritte bei Polymeren mit anorganischem Rückgrat hervorgehoben, es wird diskutiert, wie die Lewis‐Säure/Base‐Funktionalisierung von Polymeren zu beispielloser Reaktivität führt, und es werden konjugierte Hybride mit spezifischen elektronischen Strukturen für die Sensorik sowie Anwendungen in Organische‐Elektronik‐Geräten vorgestellt.

The past decade has witnessed tremendous advances in the synthesis of polymers that contain elements from the main groups beyond those found in typical organic polymers. Unique properties that arise from dramatic differences in bonding and molecular geometry, electronic structure, and chemical reactivity, are exploited in diverse application fields. Herein we highlight recent advances in inorganic backbone polymers, discuss how Lewis acid/base functionalization of polymers results in unprecedented reactivity, and survey conjugated hybrids with unique electronic structures for sensor and device applications.

Poly(thienylene vinylene)s (PTV's) are early examples of conjugated polymers but have not been extensively studied when compared with closely analogous polythiophenes. PTV's synthesized through previously reported techniques are similar in structures that contain various alkyl or alkoxy side-chains that exert limited impact on the polymer electronic properties. Herein, we report the preparation of a series of regio-regular PTV's (rr-PTV's) bearing cross-conjugated sidechains through ADMET polymerization of a common brominated di(thienylene vinylene) (DTV) monomer followed by PPM reactions on the resulting brominated PTV. These new polymers contain a bulky silyloxy alkyl side-chain and a functionalized thiophene moiety on every main-chain thiophene unit, and their regio-regular placement is confirmed by NMR spectroscopy. The thienyl based side-groups broaden polymer absorption ranges and at the same time lead to uncommon emission properties that are results of light-induced charge transfer events between the polymer main-chains and side-chains. Removal of the silyl groups on one of these rr-PTV's led to insoluble materials and x-ray diffraction experiments on the collected solids displayed distinct scattering peaks that are absent from similarly functionalized regio-random PTV's reported previously, thus suggesting better crystallinity originated from regio-regularity.
