The low-energy nature of these vibrations makes it difficult to access them experimentally, which is why we still lack clear molecular design rules to control and reduce dynamic disorder. In this study we discuss the promising organic semiconductors rubrene, 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothio-phene and 2,9-di-decyl-dinaphtho-[2,3-b:20,30-f]-thieno-[3,2-b]-thiophene in terms of an exceptionally low degree of dynamic disorder. In particular, we analyse diffuse scattering in transmission electron microscopy, to show that small molecules that have their side chains attached along the long axis of their conjugated core are better encapsulated in their crystal structure, which helps reduce large-amplitude thermal motions. Our work provides a general strategy for the design of new classes of very high mobility organic semicond...

Evaluation for Offices is one way of getting emotions or feedbacks from clients. A person's response serves as an assessment of the quality of higher education standards. For the administrators to gather feedback from the clients/customers regarding their satisfaction or performance inside the offices or department premise, eSurMent was used as a gathering data tool. The study identifies the strengths and weaknesses of Educational Institution Services based on users' positive and negative responses. It provides a sentiment score from the qualitative data and a numerical response rating from the quantitative evaluation data, and a description of the evaluation results from users. Sentiment analysis is one way of surveys and polls to analyze the responses that researchers found to determine ...
