Abstract

Hemicellulose polymers are well-known for their applications in biology, but much less in the field of optics, and especially for their applications in fluorescence. On the other hand, original tetrazines that display intense fluorescence due to energy transfer from an absorbing “antenna” have been already described by some of us. In this study, we show that hemicellulose polymers are an host of choice for tetrazine fluorophores, likely due to their remaining locked within the hydrophobic nanodomains of the polymer, thus displaying an impressive increase in the emission quantum yield. We report an application to photon down-shifting in a classical organic solar cell (OSC), as well as an application of these highly emissive doped polymers.

高浓度下移四嗪对半纤维素聚合物中OSCs的紫外线防护太阳能电池的合成、性能和性能

半纤维素聚合物在生物学上的应用是众所周知的，但在光学领域的应用却很少，尤其是在荧光方面的应用。另一方面，由于吸收“天线”的能量转移，原始的四嗪显示出强烈的荧光，我们中的一些人已经描述过了。在这项研究中，我们表明，半纤维素聚合物是四嗪荧光团的首选宿主，可能是因为它们仍然锁定在聚合物的疏水纳米域内，从而显示出令人印象深刻的发射量子产率增加。我们报道了光子下移在经典有机太阳能电池（OSC）中的应用，以及这些高发射掺杂聚合物的应用。

期刊介绍： This journal is an international medium for the rapid publication of original research papers, short communications and subject reviews dealing with research on and applications of electronic polymers and electronic molecular materials including novel carbon architectures. These functional materials have the properties of metals, semiconductors or magnets and are distinguishable from elemental and alloy/binary metals, semiconductors and magnets.
