“…Previous studies used cholesterol to add chirality to the block copolymer. Other groups have used cholesterol to add liquid crystallinity (a liquid crystalline material is one that is orientated like a solid but flows like a liquid) to the polymer [150][151][152][153][154][155][156] and were shown to mimic the physical dynamic properties and functionality of biological membranes [153,157,158]. While there are no reports showing the effect of liquid crystalline materials on cell adhesion, there is potential for this type of polymer in implantable devices, as cholesterol could enhance cell adhesion by intercalating into a cell membrane [159].…”

Conducting polymers (CPs) are organic semiconductors that have gained popularity in more recent years as components of bioelectronic devices designed to electrically communicate with biological environments. Synergy between the material and biological tissue, both on a structural and functional level, is paramount for the proper performance of an implantable biomedical device. As such, significant progress has been made on understanding the fundamental impact of the molecular and macro structure of CPs on their functional properties such as conductivity and charge mobility. At the same time, the development of a variety of synthetic approaches has yielded a library of CPs with improved mechanical and electronic properties. Specifically, chemical biofunctionalization of CP films has significantly decreased the foreign body response, the main contributor to device failure. Therefore, this review covers the advances and challenges made in the chemical biofunctionalization of CP films for potential implantable devices. This is achieved by covalently attaching the biocompatible or biofunctional group to the CP backbone via a reactive functional group to create a material with physical and electronic properties that better matches biological tissue. A perspective is presented that this synthetic chemistry approach to biofunctionalization is valuable for the integration of CPs into commercial implantable bioelectronic devices.

“…So far, there are no reports, to the best of our knowledge on polysiloxanes coupled with side-chain dimers to form side-chain liquid crystal polymers that exhibit N tb phase behavior. Though it is noted that a number of polymers have been reported that carry di-mesogenic side chains, mainly based on malonate branching groups [13][14][15]. The N tb phase for dimers is known to show often non-typical optical defect textures; also, it is not easy to distinguish the N tb from the nematic phase by X-ray diffraction.…”

A new mesogenic non-symmetric dimeric monomer with a terminal olefin function, forming a twist bend nematic (Ntb) as well as a nematic (N) phase, was synthesized, using an enhanced synthetic methodology, which avoids isomerization of the terminal double bond in the preparation of the dimer. This monomer was attached to a pentamethyldisiloxane group, resulting in the SmA LC phase behavior of the ensuing material. Linking the monomer to a siloxane main chain resulted in nematic phase behavior. Detailed studies with the Ntb phase forming dimer DTC5C7 show full miscibility of the dimer and the new LC polymer in the LC state, suggesting that the side-chain LC polymer forms a Ntb phase as the low-temperature nematic phase. Copolymerizing the monomer with a cyanobiphenyl-based monomer allows us to tune the glass transition and phase behavior further.
