Square‐planar bis(dithiolene) complexes are characterized with a planar delocalized structure and a strong and tunable near infrared (NIR) absorption; they are highly stable under laser irradiation, and their conversion efficiency (light to heat) reaches up to 40–50 %. Their involvement in soft matter, namely liquid crystals, gels, and nanoparticles, opens many possibilities to control the actual state of a material, particularly under light irradiation. Thus, liquid crystalline phases can easily be modified, (i) with temperature to modulate the extended magnetic interactions of paramagnetic complexes, or (ii) under laser irradiation to unravel these remarkable photothermal properties, toward the development of light‐responsive materials. Dithiolene complexes can be also functionalized to produce very effective gelation agents, while the photothermal effect can be used to destabilize at will their supramolecular organization. Besides photothermal therapy, new therapeutic agents were also developed for photo‐controlled drug delivery and bioimaging, combining chemotherapy and phototherapy. Hydrophobic complexes were accordingly designed for their encapsulation in block copolymer nanoparticles for photothermal therapy and photo‐controlled drug delivery under laser irradiation. This class of complexes can be also used as exogenous contrast agents for photoacoustic bioimaging.

(照片)在软物质中对功能性二硫杂环戊烯络合物的热刺激

方平面双(二硫代戊二烯)络合物具有平面离域结构和强且可调的近红外(NIR)吸收的特征。它们在激光辐照下非常稳定,其转换效率(从光到热)高达40–50%。它们参与软物质,即液晶,凝胶和纳米颗粒,为控制材料的实际状态提供了许多可能性,尤其是在光照射下。因此,可以很容易地对液晶相进行修饰,(i)用温度调节顺磁性配合物的扩展的磁相互作用,或(ii)在激光辐照下解开这些显着的光热特性,从而发展光响应性材料。还可以将二硫烯复合物官能化以产生非常有效的胶凝剂,而光热效应可用于破坏其超分子组织的稳定性。除光热疗法外,还开发了用于化学疗法和光疗相结合的光控药物输送和生物成像的新型治疗剂。因此设计了疏水复合物,以将其包封在嵌段共聚物纳米颗粒中,以进行光热疗法和在激光照射下进行光控药物递送。这类复合物也可用作光声生物成像的外源性造影剂。因此设计了疏水复合物,以将其包封在嵌段共聚物纳米颗粒中,以进行光热疗法和在激光照射下进行光控药物递送。这类复合物也可用作光声生物成像的外源性造影剂。因此设计了疏水复合物,以将其包封在嵌段共聚物纳米颗粒中,以进行光热疗法和在激光照射下进行光控药物递送。这类复合物也可用作光声生物成像的外源性造影剂。
