项目摘要

In today's market, sun care products are expected to be multifunctional providing nourishment and anti-ageing options as well as UV protection. Sun care global market is set to rise 6.4% by 2018, which currently accounts for 2% of global beauty and personal care industry worth of USD 454bn. Global skin-ageing care sales in 2015 were USD 115bn and forecast to rise to USD 154bn by 2021. Formation of the free radicals under sun exposure is one of the main reasons for skin ageing and skin cancer development. Common sunscreen formulations include antioxidants, ultraviolet (UVB/UVA) and broad band filters providing the protection from free radicals and sun burns. Solar radiation of vls/IR region can penetrate skin deeper. Upon vls/IR radiation, bio-molecules accumulated in skin and heat shock also induce formation of the free radicals. Current formulations are based on the reflection and scattering properties and almost on no absorption in the IR region except for water absorption bands. NIR absorbers (700-1500nm) can offer an alternative to the current formulations. The project is based on design, synthesis and characterisation of the novel optical filters capable of far-red visible and NIR absorption. The brief states that the synthetic methodology to be employed should enable the synthesis and the structural characterisation of NIR dyes with defined properties such as transparent/ off colour in the visible region and strong absorption in region of 700-1100 nm. A number of routes are available to prepare NIR dyes with the desired characteristics to meet the criteria outlines. Due to the nature of the product and potential for a wide variety of eventual applications possible, the dyes should provide no negative effect on the visual characteristics of the formation and can be turned to give the effect at a desired level.

在今天的市场上，防晒产品预计将是多功能的，提供营养和抗衰老的选择，以及紫外线防护。到2018年，全球防晒市场将增长6.4%，目前占全球美容和个人护理行业的2%，价值4540亿美元。2015年全球皮肤老化护理销售额为1150亿美元，预计到2021年将增至1540亿美元。在阳光照射下形成的自由基是皮肤老化和皮肤癌发展的主要原因之一。常见的防晒配方包括抗氧化剂、紫外线（UVB/UVA）和宽带过滤剂，提供对自由基和晒伤的保护。vls/IR区域的太阳辐射可以更深地穿透皮肤。在vls/IR辐射时，皮肤中积累的生物分子和热休克也诱导自由基的形成。目前的配方是基于反射和散射特性，并且除了水吸收带之外，在IR区域几乎没有吸收。NIR吸收剂（700- 1500 nm）可以提供当前配方的替代品。该项目是基于设计，合成和表征的新型光学过滤器能够远红外可见光和近红外吸收。该摘要指出，所采用的合成方法应能够合成和结构表征具有定义特性的NIR染料，例如在可见光区的透明/变色和在700-1100 nm区域的强吸收。有许多途径可用于制备具有所需特性的NIR染料，以满足标准概述。由于产品的性质和可能的多种最终应用的潜力，染料应该对地层的视觉特性没有负面影响，并且可以被转化为以期望的水平提供效果。
