دل کھول کے اگے رکھ
جانے بھانویں یار نہ ککھ
جے عشق انگاری ہووے
اوہ جاندی اک دن بھکھ
’’اَلعشقُ نار‘‘ آیا
ہن مزہ ہجر دا چکھ
جد حسن انوکھا ہووے
دل ایویں جاندا بھکھ
وچ پانی سوٹا ماریے
اوہ کدی نہ ہوندا وکھ
جیہڑے ہیسن عاشق سچے
اوہو ہو گئے ساتھوں وکھ
نت جادو پئی جگاوے
تیری ہیریاں ورگی اکھ
Bhim Sen Sacher informed Jenkins about the destruction caused by arson in Lahore. Akbari Mandi, Chune Mandi, Chauhatta Basti, Bhagat Singh Basti, Kucha Kagzian and Pipal Vehra had been burnt down. The fire brigade could not cope with those vast and dispersed areas. If someone tried to extinguish the fire he was shot at by the police. Bhim Sen Sachar suggested that the only way to save Lahore was to impose martial law in the city. He hoped that the Governor would take that step immediately.64 Jenkins thanked Lala Bhim Sen Sachar and Gokul for their letters informing him about Lahore. Jenkins explained that fire brigade had done a good job in spite of constraints and difficulties. He believed that all communities had access to incendiary materials, and could use it without detection by traversing joined roof-tops. Throwing fire-balls from one house to another was wreaking devastation. Checking trouble of that kind was not an easy job, but searches were carried out and culprits were arrested.6
This research work is based on synthesis of various coumarin derivatives and structure of those derivatives were confirmed by using different spectroscopic techniques like IR, λmax, 1H NMR, 13C NMR ESI-MS etc. These derivatives were then utilized to make different metal complexes with Cu and Ag metals. The synthesized complexes were then characterized by using IR, atomic absorption; thermal gravimetric analysis, powder XRD, mass spectrometry and their magnetic properties were also studied by VSM. Finally coumarin and coumarin derivatives and all metal complexes (M= Cu, Ag) were used against different pathogens to study their antibacterial activity. All coumarin derivatives and metal complexes shown antibacterial activity against any one of the bacterial strain and inhibited their growth.Metal complexes found to be more efficient against bacterial strains than coumarin ligands.
