Photophysical characterization of the 9,10-disubstituted anthracene chromophore and its applications in triplettriplet annihilation photon upconversion
Molecules based on anthracene are commonly used in applications such as OLEDs and triplet–triplet annihilation upconversion. In future design of blue emitting materials it is useful to know which part of the molecule can be altered in order to obtain new physical properties without losing the inherent optical properties. We have studied the effect of substitution of 9,10-substituted anthracenes...
متن کاملMesoscopic quantum emitters from deterministic aggregates of conjugated polymers.
An appealing definition of the term "molecule" arises from consideration of the nature of fluorescence, with discrete molecular entities emitting a stream of single photons. We address the question of how large a molecular object may become by growing deterministic aggregates from single conjugated polymer chains. Even particles containing dozens of individual chains still behave as single quan...

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...

Conjugated Polymers as Fluorescence-based Chemical Sensors
Reported by Jay Wackerly November 1, 2004 INTRODUCTION A chemical sensor is a molecule that interacts with another molecule giving a measurable signal in response. Chemical sensors based on conjugated polymers have received a great deal of attention due to their ability to detect analytes at low concentrations. Fluorescence quenching provides an effective means for detection because of the extr...
