“…The synthesis of polymers with pendant luminescent groups can occur either through attaching the luminescent group before the polymerization step or by doing so after the polymer is formed via postpolymerization functionalization . An advantage to functionalizing prior to polymerization is that greater control over the degree of functionalization is available, with each monomeric unit containing the chemosensor of interest.…”

There is great need for stand-alone luminescence-based chemosensors that exemplify selectivity, sensitivity, and applicability and that overcome the challenges that arise from complex, real-world media. Discussed herein are recent developments toward these goals in the field of supramolecular luminescent chemosensors, including macrocycles, polymers, and nanomaterials. Specific focus is placed on the development of new macrocycle hosts since 2010, coupled with considerations of the underlying principles of supramolecular chemistry as well as analytes of interest and common luminophores. State-of-the-art developments in the fields of polymer and nanomaterial sensors are also examined, and some remaining unsolved challenges in the area of chemosensors are discussed. CONTENTS 4.4.

The characteristics of surface and interface of nanocomposites are favor for exerting some functional properties and widening new applications. Some low-dimensional materials generally have abundant chemical groups and reaction activities. These surface chemical groups of nanomaterials provide a large platform to develop new nanocomposites and applications by surface chemical reaction and surface reconstruction of another kind of materials. Among so many hot-fields materials, graphene and its nanocomposite are developed rapidly. The graphene oxide not only has good charge transferring property, but also has abundant chemical groups on its surface, such as, -COOH, -OH and epoxide group. Therefore, graphene oxide is a good candidate substrate for further constructing other functional materials in nanoscale. The graphene oxide and pyrene derivatives were selected as representative materials for studies. Assembly of pyrene containing –NH2 groups on the surface of graphene oxide was carried out. A series of characterizations were performed by SEM (scanning electron microscopy), TEM (transmission electron microscopy), the FTIR (Fourier-Transform Infrared ) spectra, The UV-Vis (Ultra-violet visible spectroscopy), photoluminescence spectra, et al. The results indicated that the UV-Vis of nanocomposite was almost covered the whole region of visible light, and the results of PL showed strong fluorescence quenching. There was strong interaction between the graphene oxide and pyrene. The photoconductivity response to weak visible light and 808 nm laser were studied based on interdigital electrodes of Au on flexible PET(polyethylene terephthalate) film substrate with casting method. The results showed that graphene oxide modified with pyrene derivatives exhibited that the photocurrent increased obviously to visible light, and photoresponse to weak 808 nm laser emerged photo-switching behavior. It would be developed the light detector to NIR, biomimetic fields or external stimuli driven nanocarriers for biomedical fields, et al.

Independent of the substrate structure and reaction conditions, 3-amino-2-cyanothioacrylamides, which contain two active electrophilic centers, were shown to interact with various active halo methylene compounds under mild conditions to afford 5-acyl-2-amino-3-cyanothiophenes as the only products. A series of new polyfunctional thiophene derivatives with a rare combination of functionalities were synthesized, and their photophysical properties were experimentally and computationally investigated. The calculated electronic characteristics of the ground and excited states were compared to the experimental results, which provided a good understanding of the relationship between the optoelectronic properties and the molecular structures. After absorption of light quanta, the systems populate an intramolecular charge-transfer (ICT) Franck-Condon state, and emission occurs from a twisted ICT minimum.
