merocyanine form. Moreover, the dynamic interconversion behavior of the form in the different chemical environments are distinct. Liquidcrystalline polymers (LCPs) containing the SPBMs cross-linked via visible light, own a photoswitchable glass transition temperature (Tg) and retain the switchable property; however, the SPBMs cross-linked via UV light will be locked at the MC state, because the molecular
基于螺吡喃的材料 (SPBM) 可以对光、热、力或 pH 值引起的刺激做出反应,这些刺激已被用作许多智能材料的触发器。在这里,合成了一种包含介晶单元的可交联 SPBM,它是浅色、非光致发光和非介晶螺旋形式,但深色、光致发光和介晶形式的部花青。此外,不同化学环境中形态的动态相互转换行为是不同的。含有通过可见光交联的 SPBM 的液晶聚合物 (LCP) 具有光控玻璃化转变温度 ( T g) 并保留可切换属性;然而,经由SPBMs UV光交联将在MC状态被锁定,这是因为分子运动在室温下冻结比规定低Ť克的LCP的。因此,基于可调T g 的可编程变色和光致发光可以赋予由 SPBM 制备的功能材料。
Micellar-incorporated hydrogels with highly tough, mechanoresponsive, and self-recovery properties for strain-induced color sensors
A new strategy is developed to incorporate hydrophobic spiropyran mechanophores into the gel network for fabricating tough and mechanoresponsive hydrogels used for strain-induced color sensor.
Photomodulation of the electrode potential of a photochromic spiropyran-modified Au electrode in the presence of Zn2+: a new molecular switch based on the electronic transduction of the optical signals
The electrode potential of a photochromic spiropyran-modified Au electrode could be reversibly modulated by UV/visible light irradiation in the presence of Zn2+, and a new molecular switch and an "AND" logic gate based on this electronic transduction of the optical signals were established.

However, it is still challenging to fabricate such soft actuators with high programmability that can be manipulated in situ with high spatial resolution. Herein, we have incorporated terminally functionalized aggregation‐induced emission active tetraphenylethene derivative and photochromic spiropyran moieties into the networks of liquidcrystalelastomers through covalent bonding to obtain the synergistic
