A review was presented to demonstrate a historical description of the synthesis of light-emitting conjugated polymers for applications in electroluminescent devices. Electroluminescence (EL) was first reported in poly(para-phenylene vinylene) (PPV) in 1990 and researchers continued to make significant efforts to develop conjugated materials as the active units in light-emitting devices (LED) to be used in display applications. Conjugated oligomers were used as luminescent materials and as models for conjugated polymers in the review. Oligomers were used to demonstrate a structure and property relationship to determine a key polymer property or to demonstrate a technique that was to be applied to polymers. The review focused on demonstrating the way polymer structures were made and the way their properties were controlled by intelligent and rational and synthetic design.

Electrochromism is the phenomenon of certain materials reversibly changing their colours or optical properties through redox reactions under an applied electric field, which has found applications in smart windows, displays and so on. The past four decades have witnessed the rapid development of electrochromic technology; however, it remains severely developmentally challenged due to its limited practical applications. Predictably, as a colour control technology that gives visual information readable by the naked eye, electrochromism should have much wider applications by applying the visualization technique to various functional devices. Indeed, some recent research findings show that integrating electrochromic technology with other advanced technologies has imparted a new strong impetus for the further development of electrochromic technology. However, a systematic review of the literature on the fusing of electrochromic technology with other advanced technologies is still lacking, demonstrating the urgent need for further studies, although there are some review papers on electrochromic energy storage devices. In this review, we systematically discuss the recent advances in the fusing of electrochromic technology with other advanced technologies, including wearable technology, thermal control technology, energy storage technology, energy harvesting technology and sensing technology. The integration modes, design principles and performance optimization for different types of interdisciplinary electrochromic devices are highlighted. Finally, an outlook concerning future trends and issues in the research field is also provided.

Dynamic sensing using intelligent composite: an investigation to development of new pH sensors and electrochromic devices

In this paper, we report on the fabrication, characterisation, and application of new polymeric displays in view of the production of new navigation screens in the transportation industry. Conjugated polymer electroluminescence devices (CPELD) have been fabricated using poly (ppheneylene vinylene) (PPV). In this study, we report on the improvement of PPV-based displays by either adding side groups to the polymer structure or by copolymerisation. The effects, of a side group employed during synthesis, on the PL (Photoluminescence), EL (Electroluminescence) profiles and the light intensity of PPV derivatives were investigated. MEH (Methoxy-EthylHexyloxy) and MCHM (MethoxyCycloHexylMethyloxy) were used as side groups. It was found that the PL and EL intensities of the MCHM-PPV were higher than those of MEH-PPV. MCHM-PPV also demonstrated higher light emission at lower potentials and currents. Using copolymers of these two polymers produced even further improvement in PL intensity.

Smart polymers with light emission ability: millennium products for intelligent displays for navigation in the transportation industry

A new computerized approach was considered for characterization and classification of different polymeric composites based pH sensors. In this approach an integrated artificial neural network (ANN)/composite was designed. Using this design we were able to create reproducible patterns and models based on the collected data. This new computerized method has advantages of being more selective and more accurate over conventional ways of data collection.
