摘要

The common approach in organic materials science is dominated by the perception that the properties of the bulk materials are virtually determined by the properties of the molecular building blocks. In this Concept Article, we advocate for taking into account supramolecular organization principles for all kinds of organic solid-state materials, irrespective of them being crystalline, liquid crystalline, or amorphous, and discuss a showcase example, that is, the utilization of merocyanine dyes as p-type organic semiconductors in bulk heterojunction (BHJ) solar cells. Despite their extraordinarily large dipole moments, which are considered to be detrimental for efficient charge carrier transport, BHJ organic photovoltaic materials of these dyes with fullerenes have reached remarkable power conversion efficiencies of meanwhile nearly 5%. These at the first glance contradictory properties are, however, well-understandable on the systems chemistry level.

7. Designing Of Lectures through Systemic Approach to Teaching and Learning, a Model for (SATL) MethodologyConcepts play a vital role in enabling chemist to deliver. The recently developing concept based teaching methods are likely to play a pivotal role towards the efforts for promoting understanding of chemical concepts and assimilation of vital theoretical foundations of chemistry. A. F. M. Fahmy and J. J. Lagowski are the leading figures in a worldwide derive towards concept building of young generation through this novel mode of teaching and learning. However, their efforts, till recently have been mostly organic chemistry specific. Nevertheless, SALTC teaching methods are equally applicable to various other disciplines in chemistry. SATLC methodology can also be thus used to overcome the problems faced by students in understanding the efficacy of any chemical entity for a specific and desired chemical action. This presentation outlines possible applications of SATLC technique to the concepts related to a number of aspects of Physical Chemistry that are to be put together in one unit for facilitating a chemical compound’s application in any chemical change desired by any researcher.

Lagowski是世界范围内通过这种新颖的教学模式建立年轻一代概念的主要人物。然而，他们的努力，直到最近已经大多是有机化学特定的。然而，saLTC教学方法同样适用于化学中的其他各个学科。因此，saTLC方法也可用于克服学生在理解任何化学实体对特定和所需化学作用的功效方面所面临的问题。本演示文稿概述了saTLC技术可能应用于与物理化学的许多方面相关的概念，这些概念将被整合在一个单元中，以促进化合物在任何研究人员所需的任何化学变化中的应用。
