Neuromorphic Light-Responsive Organic Matter for in Materia Reservoir Computing. [PDF]

Adv Mater
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

Visible light-responsive azo-based smart materials: Design, performance, and applications in energy storage. [PDF]

Smart Mol
Azobenzene and its derivatives are the most extensively investigated and applied molecular photoswitches, which can undergo reversible transformation between trans and cis isomers upon irradiation with light at specific wavelengths. Through structural geometry transformation, the property alterations can be integrated into smart materials to meet ...

Visible‐light‐switchable azobenzenes: Molecular design, supramolecular systems, and applications

Natural Sciences, Volume 3, Issue 1, January 2023., 2023
Abstract Photocontrol of functional molecules and supramolecular systems provides promising directions for the development of innovative materials and technologies. Reversible photoswitches that can isomerize among different states play a vital role in such photoresponsive systems. However, the commonly used UV light for triggering the isomerization of

Solar‐Thermal Energy Conversion and Storage Using Photoresponsive Azobenzene‐Containing Polymers

Macromolecular Rapid Communications, Volume 41, Issue 1, January 2020., 2020
Solar energy conversion and storage using photoresponsive azopolymers are reviewed. Light irradiation can induce trans‐to‐cis isomerization of azopolymers. Because cis azobenzene has a higher energy level, light energy is stored in the cis isomer. Cis‐to‐trans back isomerization results in heat release.

Reversible Shaping of Microwells by Polarized Light Irradiation

International Journal of Polymer Science, Volume 2017, Issue 1, 2017., 2017
In the last years, stimuli‐responsive polymeric materials have attracted great interest, due to their low cost and ease of structuration over large areas combined with the possibility to actively manipulate their properties. In this work, we propose a polymeric pattern of soft‐imprinted microwells containing azobenzene molecules.

Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

Polarization‐Driven Molecular Alignment of Azopolymer for Dual‐Encrypted and Moiré Animation‐Based Anti‐Counterfeiting

Advanced Functional Materials, Volume 35, Issue 31, August 1, 2025.
A multi‐layered anti‐counterfeiting platform is developed based on an azopolymer (PAzo) system. By leveraging the molecular orientation control of PAzo under linearly polarized light (LPL), encrypted patterns are fabricated that remain invisible under standard conditions and require polarized optical microscopy (POM) for decryption.
