Fluorometer for material characterization

荧光在我们的研究项目中是必不可少的，目前的应用是让我们能够获得具有足够性能的荧光仪。这台新仪器将取代已有15年历史的SPEX Fluorolog 2荧光仪。该荧光仪将用于：i)评估一种可设计为pH和光敏的新型脂质体的渗透性；ii)确定膜干扰剂对脂质双层渗透性的影响；iii)研究脂质-蛋白质相互作用中的脂质专一性；iv)获得与有机金属发光器件(OLED)相关的新过渡金属化合物和无机材料的基本光谱信息，包括荧光光谱和量子产率。以及v)确定适合太阳能电池器件的聚(2，7-咔唑)衍生物的吸收/荧光性能，以便优化计算得到的结构，并提高这些材料中的电荷迁移率和发光效率。*所有这些资助的项目绝对需要每天都能获得可靠和高效的荧光仪。我们必须提供资金来更换我们已有15年历史的机器，以更有效地执行我们的实验，扩大UV可用的波长范围，并防止在短期内由于过时系统故障而停止这些项目的情况。

Fluorescence is essential in our research programs and the present application is to give us access to a fluorometer with adequate performances. This new instrument will replace an outdated 15-year old SPEX Fluorolog 2 fluorometer.  The fluorometer will be used: i) to assess the permeability of a novel family of liposomes which can be designed to be pH- and light-sensitive, ii) to determine the effects of membrane-perturbing agents on lipid bilayer permeability, iii) to investigate lipid specificity in lipid-protein interactions, iv) to obtain fundamental spectroscopic information, including fluorescence spectra and quantum yield, on new transition metal compounds and inorganic materials relevant for applications as Organometallic Light Emitting Devices (OLEDs), and v) to determine the absorption/fluorescence properties of poly(2,7-carbazole) derivatives suitable for solar cell devices, in order to optimize the structures obtained from calculations and to improve charge mobility and luminescent efficiency in these materials.  All these funded projects absolutely required a daily access to a reliable and efficient fluorometer.  Funds to replace our 15 year old machine are essential to perform our experiments more efficiently, to extend the wavelength range available to the UV, and to prevent in the short term a situation where these projects would be stopped because of a breakdown of the outdated system.
